Need Help

Hello everybody, i’m newi n Corona development, but i made a few small and easy apps, now i’m facing a a big one and i don´t know how to handle the camera events, i´ve searched but i did not find anything.
Can I handle camera events with Corona SDK? Can i made my app to take pictures?
How is this done?
Can I handle other device´s processes like making a phone call or display the contacts list?
if this is possible, do i need special libraries? which ones? thank you for everything, and sorry for my english [import]uid: 159859 topic_id: 30145 reply_id: 330145[/import]
